Re: [Ltib] Auestion regarding ltib.preconfig configuration changes and how to have LTIB follow it

[Stuart Hughes]

Hi Peter,

From memory; you're correct once you've run ltib it will not look at 
ltib.preconfig any more.  You'd need to put the system back in the 
default state (distclean).  Alternatively you should be able to add the 
needed packages using the  ./ltib --hostcf -m config
When you're done,  you can copy the result back to ltib.preconfig for a 
cold-build.

One thing to watch out for though is that when you run ./ltib --hostcf 
-m config it takes notice of all the collateral dependencies (intended 
for the target) and so the list of package you end up installing is more 
than if you just enabled the single packages in the ltib.preconfig file 
by hand.

Regards, Stuart
